Homeless families unable to find shelter have begun returning to Logan International Airport in Boston. 

Families began arriving at the airport Monday night and early Tuesday, with some sleeping outside the terminal because of concerns of being thrown out. 

The state banned sleeping in the terminal in June when dozens of families began staying overnight on the floor of Terminal E.  Some in the group had been to a family welcome center in Quincy on Monday, but say they headed to Logan when no other options were available.
